You need to learn to stop comparing yourself to others. Easier said than done, but, you need to realize that everyone is different. I'm still trying to work on this myself because I always see other classmates doing so well and getting high marks and it makes me feel down about myself. But, I have been working on reminding myself that I am different from them and I have my own journey. My classmates are not me and I don't need to be like them. I'm now focusing on myself rather than comparing myself to them. Focus on yourself more and stop worrying about other people. Try mindfulness meditation to help you calm down before and after the test. Try not to pressure yourself too much before the test. Again, easier said than done but it would really help. If it helps, try going to therapy.
Yes, i mean atleast the school years almost over
Answer:
Myelinated Axons; leak channels are insulated by myelin leading to less loss of current flow and better conduction velocity. Ion channels omly located at nodes of ranvier; thus signal has sultatory conduction along myelin sheaths and jumps and move much quicker
Demyelinating diseases; along locations where myelin sheaths once was current links occur and conduction slows, the signal cannot make it very far because it looses energy as it travels through the axon
Unmyelinated axon; Ion channels are sequentially placed all along axons; thus it takes longer to send signal down axon. the energy isn't leaked out, it still contains the same signal but it is simply slower. distance between voltage gated channels needs to be small enough so local current flow can depolarize the membrane.
N/B; Harder to generate action potential in demyelinating disease
axon diameter( bigger diameter= less resistance= faster current).
